I found an interesting Web site about yoga for people who are hurting.
http://www.extensionyoga.com/
I know that many types of exercise are really hard when joints are hurting -- that was one of my biggest problems before my two hip surgeries, especially as things got worse and worse. I did get some relief from some simple yoga moves, though, and I think even just learning how to do the yoga breathing helped me with the pain both before and after surgery. I also found out that anything that I could do was worth a try -- if my hips hurt too much to walk, at least I could do some arm exercises, etc., and I think that really helped me when I had to get around on crutches and so forth.
Also I think there is a lot of good information about our bodies and how they work. So check it out.
